lxfb: extend PLL table to support dotclocks below 25 MHz
Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
MHz. These are needed for small LCDs (e.g. 320x240). Also inserts some
intermediate steps between pre-existing frequencies.
Andreas says:
Without this patch, I get the following (correct) output from the lxfb
and console code:
[ 0.939827] lxfb 0000:00:01.1: 16384 KB of video memory at 0xfd000000
[ 1.009194] Console: switching to colour frame buffer device 150x56
Without it, the cols/width is screwy (and I get a blank white screen):
[ 20.706836] lxfb 0000:00:01.1: 16384 KB of video memory at 0xfd000000
[ 20.788538] Console: switching to colour frame buffer device 100x40
